MANUFACTURE OF COKE AND APARATUS THEREFOR.

with limited access of air in closed sta11s,;

according to the method in' which the coal iscarried on trucks which are loaded outside the stall, when loaded wheeled into the stall, and when the charge is coked, wheeled out of the stall and the coke quenched and discharged.

In practice the stalls are built to accommodate each one truck, but they might be built to accommodate each two or more truoks.

In the accompanying drawing Figure l is a central longitudinal section through the stall with a loaded truck inclosed therein; Fig. 2 is a perspective View of the truck body showing the detail structure of the cellular tray and cellular coamings; and

Fig. 3 is an' end elevation of a stall with end doors closed on a` loaded truck, portions of the truck body being shown in section to illustrate the 'structure of the tray and its coamings.

The stall consists of two side walls A and an arched top B built of brickwork and suitably reinforced or stayed and structurally adapted to withstand the temperature necessary for the coking of coal within the stall. A line of rails YY is laid through the stall on iron sleepcrs, these rails being continued at one end of the stall to the location of suitable loading appliances, and at the otherend to the location of suitable quenching and discharging applia'nces.

Two stay posts VV are erected at either end of the stall and these are brace-bolted together in the manner shown for the purpose of supporting the brickwork structure and providing supports and runways for the stall doors. The door and frame construction at either end of the stall is similar. A smoke fine C is constructed in the top of the arch B for discharging gaseousand vaporous products of combustion and providing Specification of Letters Patent.

a means whereby the same may be drawn off for reduction to commercial products.

The truck 0 comprises an under frame ou four or more wheels and a cellular tray body with fixed coamings on two ends and one side thereof, and a hinged coaming of special Construction on its second side. The wheels and underframe of the truck come completely within the stall, while the tray body and its side and end coamings eXtend to or slightly beyond 'the ends of the stall, where it is met by the upper and lower doors of the stall, which, during the coking operation, are closed so as to exclude inlet or out let drafts. The tray and coamings of the truck body are cellular. They are constructed of iron plates trained on I-bars and 'channel bars; air vents are made in the outer shell plates to allow air to pass through the cellular spaces, entering at' the vents in the end coaming of the truck projecting beyond one end ot' the stall, and

passing out of thevents in the end coaming I of the truck projecting at the other end of the stall.

L is an outer end late of the truck, and are ventilating holes serving the cellular bottom E of the tray. Air passes into the cellular bottom of the truck body through the holes E at one end thereof and hot air finds exit through corresponding holes at the other end of the truck body. The walls or coamings of the tray are similarly constructed cellularly, as shown at J. Air enters the cellular coaming at one end of the tray body at K and after traversing it passes therefrom through the holes G into the cellular space J in one of the side coamings. Thence it passes back through the cellular coaming at the other end of the truck, and escapes outward to atmosphere by holes in the outer wall thereof, corresponding with the inlet holes K. The hinged side coaming of the truck body (M) is mounted independently of the end coamings so as to hinge outward to facilitate the dischargingof the truck. The other side coaming is thus in the same cooling air circuit as the end coaming. The ends of this hinged coaming are pierced with air holes F. Air enters through them from atmosphere at one end of the truck and hot air passes out of corresponding holes at the other end of the truck.

The upper door N of the stall is slidable in runways in the posts V. lt is moved to slide it open or closed by lines S running over sheave rollers T, and is counterbalanced by weights (not shown) hung on the ends of said lines. The lower doors P of the stall are hinged doors pntled on the lower ends of the frame V. All the doors are fitted to make a fair fit With the chamber brickwork and with the truck tray and end coamings,

'so that tight working `joints may be made charge is lighted before the doors are closed.

After the doors are closed, further admisson of air is regulated by the dampers U, of which-any required number may be provided in the upper doors N. The outlet draft through the up take C is also controlled by a damper therein (not shown). The doors N and PP close neatly against the under side and top side of the protruding ends and coamngs of the truck body, leaving the outerfaces of said ends and'end coamings exposed to external atmosphere to facilitate inflow and exit of air for the cooling of the truck body. After combusti on is completed and the charge has been converted to coke, the doors are opened and the truck wheeled out on the rails YY and the burning coke quenched and afterward discharged. The truck may then be refilled for another burning.

To facilitate truck handling, the-rail track is either made continuous, so that the trucks may be worked in continuous circuit, or

mesec@ turnouts are .provided to permit trucks to be shunted to the coal recharging site after they have been discharged at the coke dumping site. i

If the temperature of the stall after one or more burnings have been completed is sufficiently high to initiate the combustion o' a fresh charge, the process may be made practically continuous without introducing fire into successive charges, by running in t'reshly loaded trucks as each finished truck is removed.

What l claim as my invention and desire to secure by Letters Patent is l. Apparatus for burning coal to coke, comprising a stall with a gas vent formed in the upper part thereof, a rail track through said stall, a truck having an end vented cellular body overhanging the ends of its' underframe, and adapted to run on said rail track, and end doors on said stall adapted to meet the body ends of said truck so as to permit said body ends to project beyond said doors and expose the cell vents therein to atmosphere.

2. In apparatusas set forth in claim 1, a I

tray body comprisng an end Vented cellular bottom and cellular coamings, of which the coaming at one side of said body is hingedly mounted on the tray independently of the other coamings thereon.

3. Apparatus for burning coal to coke comprising a closed stall provided with fireproof doors at its ends, an end-vented cellular body truck within said stall, said doors being adapted to 'close upon the truck in such manner as to leave the vented ends of the body thereof exposed to atmosphere.

In testimony whereof I have signed my nameto this specification in the presence of two subscribing witnesses.
